Add individual automake checks

Replace the sanityTest script with individual automake test scripts.
These use the same expected test data as the CMake tests, as well
as the same test names.  The individual test output is stored
in expected/${test}.log, and the test log in scripts/${test}.log,
including the diff between the observed and expected output.  This
makes diagnosing and fixing tests much easier.
